Central processing unit (CPU)

Memory unit

Input devices

Output devices

Central Processing Unit (CPU):

CPU plays the key role in a computer by carrying out instructions of a computer program.

It performs all the basic logic, arithmetic, controlling and input/output operations that are specified by the instructions.

The CPU comprises of two units, Arithmetic logic unit (ALU) and control unit (CU).

Memory unit:

Once computer program instructions set are transformed into machine code by CPU, the machine code is stored in memory.

Then the CPU fetches the required data and instructions from memory, perform the required operations and then sends the result and next set of instructions back to memory.

Input devices:

The devices used by the user to feed information to computer, such as a hard drive, keyboard, or a networking card.

These devices get the data from outside world into computer in the way that human eyes and ears bring the data to brain.

Output devices:

Output devices are used by computer to deliver the information to the user, such as a monitor, printer, and speaker.

The CPU takes the machine code present in memory and converts it into a format that is required by monitor’s hardware.

Then the monitor’s hardware alters that information into different light intensities such that words or pictures are seen.

Students have asked these similar questions

We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.

Consider the following Turing Machine (TM). Does the TM halt if it begins on the empty tape? If it halts, after how many steps? Does the TM halt if it begins on a tape that contains a single letter A followed by blanks? Justify your answer.
